The present invention relates to an incandescent light bulb device in which each incandescent light bulb is lit.

[Conventional technology]

Incandescent light bulbs have no polarity due to their operating principle. For this reason, in conventional lighting devices using incandescent light bulbs, each incandescent light bulb lights up no matter which direction current is applied to it.

[Problem that the invention attempts to solve]

However, in this way, each incandescent light bulb lights up no matter which direction the current is applied to it. For example, if a plurality of incandescent light bulbs are attached to a strip wire having two conductors, and these light bulbs are connected to the two wires, respectively. If connected, all bulbs will always turn on and off at the same time, causing incandescent bulbs to turn on and off at the same time.
It was not possible to divide the lights into two groups and turn the lights on and off for each group independently. In order to independently turn on and off the two groups of incandescent bulbs, at least three conductive wires were required.

[Purpose of invention]

The present invention was made to solve the above-mentioned conventional problems.Each incandescent bulb lights up only when current is passed in a predetermined direction, and multiple groups of incandescent bulbs can be independently connected using a small number of conductors. To provide an incandescent light bulb device that can be turned on and off, can easily change the polarity of each light bulb, does not require much effort in wiring work, is convenient to handle, and has an excellent appearance.

[Means for solving problems]

The incandescent light bulb device according to the present invention has a generally cylindrical shape having a band-shaped electric wire having at least two conducting wires and a bottom, and a plurality of incandescent light bulbs attached to the band-shaped electric wire with the bottom in contact with the surface of the band-shaped electric wire. socket bodies and these socket bodies to each other.
A pair of sockets are attached at 180 degree angles, one end of which is along the inner surface of the socket body, and the other end of which is drawn out from the bottom of the socket body and connected to the conductive wire. an incandescent light bulb having a terminal, a plurality of generally cylindrical light bulb supports, each having a pair of lead wires, and attached to each of the light bulb supports; and a diode with either an anode side or a cathode side lead wire connected to one lead wire of the incandescent light bulb, and the other lead wire of each of the incandescent light bulbs and the other lead wire of the diode are connected to one lead wire of the incandescent light bulb. The light bulb support is pulled out from the bottom of the light bulb support and bent back along the outer surface of the light bulb support, and each of the light bulb supports includes a bent back portion of the lead wire of the incandescent light bulb and the diode. is removably fitted to the inner surface of each of the socket bodies while being sandwiched between the outer surface of the light bulb support and the socket terminal.

[Effect]

In the present invention, the diode conducts current only when a current is applied in a predetermined direction, and the current flows to the incandescent light bulb connected to the diode, causing it to light up. Therefore, multiple groups of incandescent light bulbs can be turned on and off independently using a small number of conducting wires.

In addition, since the incandescent light bulb and diode, which are already connected to each other, are supported by the light bulb support, the diode can be connected to the power supply simply by attaching the light bulb support to the socket, so wiring of the diode to the power supply can be done one by one. There's no need.

Furthermore, since the incandescent light bulb and the diode are integrated through the light bulb support, the incandescent light bulb and the diode can be handled as if they were one element, which is convenient for handling.

Furthermore, since the diode is housed within the bulb support, it is not visible from the outside and is aesthetically pleasing.

Furthermore, by changing the fitting position of the light bulb support relative to the socket main body by 180 degrees, the polarity of the diode relative to the socket and, in turn, to the conducting wire of the strip electric wire can be easily changed.

FIG. 6 is a circuit configuration diagram showing the electrical connection relationship of this embodiment. As shown in this figure, each light bulb support 1 has a diode 3 attached to each light bulb 2 connected to a strip wire 5. Each socket 4 is connected alternately in opposite directions to the conductors 5c and 5d.
is installed on. And the conductive wires 5c, 5d
are connected to output terminals 6a and 6b of the power source 6, respectively. Here, this power supply 6 is designed to output a current of opposite polarity at every fixed period T, as shown in FIG.

Next, the operation of this embodiment will be explained.

Now, if the output terminal 6a of the power supply 6 is on the positive side and the output terminal 6b is on the negative side, the odd-numbered diodes 3, 1, 3, 3, ..., 3, 2 _o-
Only ₁ conducts current, even numbered diodes 3,
2, 3, 4, ..., 3, 2n do not conduct current, so the odd numbered bulbs 2, 1, 2, 3, ..., 2,
2 Only _o-1 lights up, even numbered bulbs 2, 2, 2,
4, . . . , 2, 2n are turned off. Conversely, when the output terminal 6a of the power supply 6 is on the negative side and the output terminal 6b is on the positive side, only the even-numbered diodes 3, 2, 3, 4, ..., 3, 2n conduct current. , odd numbered diodes 3, 1, 3, 3,...
..., 3, 2 _o-1 does not conduct current, so the odd-numbered bulbs 2, 1, 2, 3, ..., 2, 2 _o-1 go off, and the even-numbered bulbs 2, 2, 2, 4,...,2,
2n lights up.

Therefore, since the polarity of the current output from the power source 6 changes every cycle T, the odd numbered bulbs 2, 1, 2, 3, ..., 2, 2 _o-1 and the even numbered bulbs 2, 2, 2, 4, ..., 2, 2n is the period T
It flashes alternately every time.

Here, in this embodiment, since the diode 3 is connected to each light bulb 2, the 2
It is possible to make each bulb 2 blink alternately using only the conductors 5c and 5d, but if the diode 3 is not connected to each bulb 2, the number of conductors connecting each bulb 2 to the power source is Unless there are at least three bulbs, each bulb 2 cannot be blinked alternately.

Furthermore, the electrical connection shown in FIG. 6 can of course be obtained by directly connecting the diodes 3 to the conducting wires 5c and 5d of the band-shaped electric wire 5, but in that case, wiring work is time-consuming. However, in this incandescent light bulb device, an incandescent light bulb 2 and a diode 3, which are connected to each other in advance, are supported by a light bulb support 1, and this light bulb support 1 is connected to a socket 4 connected to conductors 5c and 5d. Since the electrical connection shown in FIG. 6 can be obtained immediately by simply mounting the diode 3, there is no need to wire the diode 3 to the conductive wires 5c and 5d.

Moreover, the light bulb support 1 is attached to the socket body 4a.
By changing the fitting position of the diode 3 by 180 degrees, the polarity of the diode 3 with respect to the socket 4 and the conducting wires 5c and 5d of the strip electric wire 5 can be easily changed.
